Zusammenfassung:PROBLEM TO BE SOLVED: To provide an exterior material for buildings which suppresses deterioration of a base material as well as excels in harmful gas-decomposing characteristics and mildew resistance-alga resistance, and to provide a photocatalytic aqueous coating liquid. SOLUTION: This exterior material for buildings is provided with the base material and a photocatalytic layer provided on the base material. The photocatalytic layer is obtained by coating the photocatalytic coating liquid and drying it. The photocatalytic coating liquid includes a photocatalytic titanium oxide particle, a niobium oxide particle, a silicone emulsion, a water-soluble copper compound and water.
